I bought a couple of these smart outlets on Amazon and love them as they pair and work well with Home Assistant, but when I installed them I noticed that they do not fit not the standard Decora sized wallplates, so I made this one.
You'll need to use the original small screws attached to the faceplate that comes with it, and also some flathead 6/32 screws to attach the outlet to the wall box.
Print upside down without supports and I recommend 5 bottom layers for this to ensure you get a sturdy plate. I used ABS but PLA should also work as long as you don't tighten the screws down too tightly.
Note that this faceplate is also oversized to match my other styles. If you need a different size please let me know and I'd be happy to upload one.
